中文摘要：

采用环氧树脂作为中间层的真空键合技术实现体材PZT与硅片键合,再利用机械化学抛光方法将PZT减薄到适当的厚度制备了PZT铁电厚膜,构成了SiO2/Si/SiO2/Epoxy/Ag/PZT/Cr/Cu形式的压电能量采集器悬臂梁结构。基于半导体光刻技术,通过湿法化学刻蚀和切片两种方法实现了PZT厚膜图形化问题,为基于体材PZT厚膜的高性能压电能量采集器的研制打下了良好的基础。

英文摘要：

Bulk PZT thick films for piezoelectric micropower harvester were prepared through bonding the bulk PZT to silicon wafer in vacuum with the epoxy resins used as intermediate adhesive layer,then the PZT piece was thinned down and lapped to a suitable thickness to prepare the ferroelectic PZT thick films,thus providing a cantilever structure of piezoelectric micropower harvester made from SiO2/Si/SiO2/Epoxy/Ag/PZT/Cr/Cu.Based on the semiconducting lithography,the micro patterning of PZT thick films was implemented via the wet chemical etching technique and dicing method.A firm foundation was therefore laid down for the research and development of piezoelectric micropower harvester with high performance.
